An electronic apparatus includes a base, a sliding member and a sliding mechanism. The sliding mechanism includes a first magnet disposed in the sliding member, and a first electromagnet disposed in the base opposite to the first magnet. The first magnet and the first electromagnet are capable of producing a first repulsive force and a first attracting force, the sliding member alternately slides back and forth between the different locations of the base driven by the first repulsive force and the first attracting force.
